Shark.blend - no working import path #1

Open RevoluPowered opened 4 years ago

RevoluPowered commented 4 years ago

Godot Version: 3.2.1 Import paths tested: FBX, GLTF2, Collada, ESCN.

Issues found:

GLTF2: patched in blender (still waiting merge, and won't be available until August) https://github.com/KhronosGroup/glTF-Blender-IO/issues/791
FBX: mesh has missing vertexes but the animation works for the percentage of mesh shown.
Collada: rigging is rotated 90 degrees and breaks animations
ESCN: same as Collada.

Hello, some comments regarding glTF:

GLTF2: default bone settings from blender to GLTF2 do not work

By default, inherit rotation is checked and inherit scale is set to "FULL". Using this default, exporter should work correctly. If this is not the case, please open an issue. Not default values are not yet taken into account, a patch is under review

If someone want more information:

In the short term to workaround this issue with the GLTF2 importer, I can patch the FBX importer to resolve our mesh issues.

Blender animations work fine from FBX too, so this would be fine once mesh is sorted our, at our end.

We would / should fix this anyway, more importers which work here is better.

FBX mesh issue (prob Godot side; will know in a bit)

I dug into this over the weekend this is because the skinning algorithm is causing faces in some cases to be invisible, but also the mesh itself is fine, removing skin and disabling the skeleton shows a non-broken mesh
